WHEEL WITH ENDLESS .RAIL.

$PECIPICATION forming part of Letters Patent No. 373,887, dated November 29, 1887.

Application filed March 21, 1887. Serial No. 231,800. (No model.i Patented in Germany May '27. 1885, No. 33,823, and July 3, 1886, No. 38,895, and in England July 8, 1886, No. 8,916.

To all whom it may concern.-

Be it known that 1, WILLIAM FENDER, gentleman, a citizen of the Republic of Argentine, residing at Buenos Ayres, in the country of the Argentine Republic, haveinvented certain new and useful Improvements in \Vheels with Endless Rails, (for which I have received Letters Patent in GreatBritain, bearing date of July 8, 1886, No.8,9l6, and in the German Empire, under date of May 27, 1885, No. 33,323, and July 3, 1886, No. 38,895,) and I do hereby de-" clare that the following is a full, clear, and exact description thereof.

The object of my invention is to produce a wheel provided with an endless rail or chain so arranged that whenthe wheel revolves part of this chain is laid down in front and raised at the rear of the said wheel.

Referring to the drawings, Figure 1 is a front view of a wheel embodying my invention. Fig. 2 is a plan sectional view of the same. Fig. 3 is a sectional view on line m m, Fig. 1. Fig. 4 are enlarged detached views of the link-fasteners. Fig. 5 is a side elevation of a wheel, showing a modification. Fig. 6 is a sectional view. Figs. 7 and 8 are plan views of the endless rail. Fig. 9 are transverse sectional views of Figs. 7 and 8.

G represents a wheel with hub B. On each side of the wheel are placed the disks E E, secured to the hub B.

D D are two cams secured to the hub, and shaped as shown.

A is the endless rail or chain, consisting of properly-shaped short pieces of steel, Fig. 4, which are fixed to a band of steel or wire rope. Outside of the said band are fixed another series of transverse rails in a similar manner; but these pieces are in such a position in respect to the inner rails that the middle of an outer rail corresponds always with the ends of two inner rails, and vice versa, as shown in Fig. 1.

L L are arms fastened to the rail A and made to slide in and out in the guideways J, fastened to the disks E E. The inner ends ofthese arms are provided with rollers M M,which revolve over the surfaces of the cams D D. A shield for the endless wheel is provided and shown, and marked a in Fig. 5. By this arrangement I am able to carry the endless rail around the traveling wheel in such a manner that it is always forced upward at the rear, carried over at the top, and placed down at the front of said wheel.

Fig. 5 shows a modification of my device. This device consists of the wheel G, rim'O around which is placed the endless rail A, secured together, as shown in Figs. 7 and 8. ais a guard to prevent the rail from sliding off the wheel, and is held in place by the arms k k. Thus when the wheel revolves and moves backward or forward the ringsare taken along with it. They roll forward and backward at the same rate as the wheel itself. This modified form of construction is simpleiy but it has the drawback that it does not allow sucha long railsurface on the ground.

Havingthus described my invention, I desire to claim- The combination, with the wheel G, of the WILLIAM FENDER.
